HOLDER FOR SENSITIZED PAPER.

Application filed March 22, 1928. Serial No. 263,826.

This invention relates to a device for use of photographers for holding sheets of sensitized paper, and has for its object to provide a holder which will be portable and will support paper sheets in a stationary position while exposed to the rays of light required for photographing.

One of the specific objects is to provide a holder of such construction that cards or paper sheets may be moved into position in the holder and removed therefrom conven iently and with great rapidity during the operation of photographing.

Another object is to provide a holder consisting of few and simple parts so that it may be manufactured at a limited expense.

With these objects in view and others to be mentioned, the invention presents a novel and useful construction, combination and arrangement of parts as described herein and claimed, andas illustrated in the accompanying drawing, it being understood that changes may be made in form, size, proportion and minor details, said changes being within the scope of the invention as claimed.

In the drawing, Fig. 1 is a plan view of the holder. Fig. 2 is a view of the rear side of same. Fig. 3 is a view of the front side of the holder, and Fig. 4 is a sectional detail showing the position of a contact-member relative to the stop-plate or guard strip.

Referring now to the drawing for a more particular description, numeral 5 indicates a rectilinear supporting-plate, and upon its upperside and inwardly of its edges is secured a holder-block 6.

Numerals 7 indicate resilient contact-members preferably actuated by springs 8 which are mounted on the sides and ends of theblock.

\Vhile the holder-block in the present instance is of rectangular form, it may have such form, in plan, corresponding to the paper sheets or cards to be placed thereon. The contact-members are preferably constructed of wire, but I do not wish to limit myself in this respect.

These contact-members project above and engage the edges of the block. Any desired number of these contact-members may be used and their upper end-portions are curved outwardly as indicated at a.

As thus described it will be seen that paper sheets a; will be suitably held on the block, the proportion of parts being such that their edges will be engaged by mean bers 7 to prevent vibration of the sheets.

By use of the device the work of photographing may proceed with great rapidity. An operator may place the sheet upon the block and after an instant of exposure may withdraw it, a groove 11 being provided iii the front edge of the block to facilitate removal of the sheet.

On account of the curved parts a of members 7, the sheets may be readily moved and disposed flatwise upon the upper face of the block and the sheets will not become cau hi: or obstructed by said members 7.

The stop-plate or guard strip 9 is of Qi'tdt advantage in operation while moving the sheets; one of their edges engages this plate before moving downward upon the block. Also by use of the Sl OP'PlHl'Q the sheets will be disposed parallel with the block to facili-- tate operation.

lVhile I have shown and described a holder-block 6 and prefer its use, said block may be dispensed with and the contactmembers 7 may have any suitable mounting so that they will project upwardly from the supporting-plate 5, said contact-members being disposed in lines corresponding to the contour of and forming an enclosure for receiving said sheets.

It will be understood that the degree of resiliency for the contact-members will be such that they will engage the edges of the sheets to prevent vibration, said degree of resiliency, however, being such that the sheets will not be Wavy or buckled.

Since the curved terminals a of the contact-members project outwardly they will not obstruct the rays of light directed to the enclosure or area between the lines of members 7 in which the sheets of paper are laid.

The use of the device will be appreciated by photographers in instances where speed and accuracy are required.

I claim as my invention,

1. In a holder for paper sheets, a supportingplate, a plurality of resilient contactmembers projecting above the supportingplate in lines conforming to the contour of the paper sheets and forming an enclosure for receiving said sheets, and a guard strip projecting upwardly from the supportingplate at the side of one of the lines of said contact-members, said contact-members having curved end-portions projecting outwardly of the area of said enclosure.

2. In a holder for paper sheets, a supporting-plate, a holder-block on the supportingplate, resilient contact-members projecting above and engaging the edges of the holderblock, and a guard strip projecting above:

and secured to a side of the holder-block.

3. In a holder for paper sheets, a supporting-plate, a holder-block on said plate, a plurality of contact-members projecting above and engaging the sides of said block and forming an enclosure for receiving said paper sheets, said contact-members having a degree of resiliency to permit engagement, with the edges of the paper sheets'without causing bucklingof said sheets.

4. In a holder for paper sheets, a supportingplate, a holder-block mounted on the top of said plate, a plurality of contact members secured to the sides and projecting above said block and forming an enclosure for receiving said sheets, said contact-mem bers having curved end-portions projecting outwardly from said block and having a degree of resiliency permitting engagement thereof with the paper sheets in said enclosure.

5. In a holder for paper sheets, a supporting-plate, a holder-block mounted on said 1,2 2 are curved end-portions and a degree of resiliency tending to cause them to engage the edges of the sheets in said enclosure.

' 6. In a holder for paper sheets, a supporting-plate, a holder-block mounted on said plate and provided, transversely, with a groove opening on its side, a pluralityof resilient contact-members at the sides and projecting above. the block to form an enclosure for receiving the sheets, and a guard strip secured to a side of the block opposite to said groove, said contact-membershaving curved end-portions projectin outwardly of the plane of said block and outwardly of the plane of said guard strip.

7. In a holder for paper sheets, a holderblock, contact-members engaging the sides and projecting above-said block and forming an enclosurefor receiving said sheets, said contact-members having outwardly curved terminals and having a degree of resiliency to permit a pressure thereof against the edges of said sheets.

8. In a holder for paper sheets, a holderblock having a groove in one ofits sides, a plurality of resilient contact-members pro jecting upwardly from the sides and having curvedend-portions extending outwardly of the plane of said block and providing an enclosure for receiving said paper sheets, and a guard strip on that side of the block opposite to said groove.

In testimony whereof, I have afliXed my signature.
